Not great. Quieter than my venom push pull for the same perf. Absolutely nothing can keep my i7 cool at this speed it seems. The H50 fails, all idle at the same temp. My fan arrangement for the H50/70 is one high speed on exhaust. Dual fans makes it loud enough to defeat the point of water, intake is a moronic heat dump that's not even an option. Most reviewers didn't even test it. While I've seen these things stay stable at 102c it really bugs me seeing mine up to 95c, even if it is stable. Yes I've tried all sorts of crazy case fan stuff to make sure it isn't from bad ambient or dead air flow, it's not. Re-seating always brings the same temps. All I can figure is it's my chip. Looking around I've seen a lot of people topping out in the 80s, but I see a few always in the 90s. I guess I'm one of those few.

So, I dont get your stance, you butchered the cooler and didnt install it as per the instructions, and you want to complain about its performance? Or you like it, it just doesnt work as you want it to?

A bit of both. I saw a number of reviews that tested with it exhausting and placed two fans on the H50 as well, so based on that I got a good idea as to what temp difference I should expect to see going from the H50 to the H70 using my fan setup on both. The difference was less than expected based on those comparisons. It seems there was a gap between theory and practice.

Ok I can understand that. From what I gathered, and my testing showed, it is better but only slightly more efficient.

That is kind of how I felt after I changed from IFX-14 to a H50 and temps got worse. So I cracked it and done a loop.

In my humble opinion, any of the AIO water coolers are not for the extremists. They are geared for the mid range clockers who either cant afford full on water but like the clean look, or those who dont have the room for a full tower.

I reversed the the fan and interestingly it only the had the effect of slowing the temperature increase at load, same ultimate temp. With every cooler I've tried I end up with about the same top heat load. It's like this chip saturates everything beyond reason. I'd really love to try a different i7 sometime to see if this thing really is just high on the leakage.
